    Recently I've owned an 08 WR450F, 11 KX450F, and now a 13 450SXF. I have to say the KTM is the cream of the 450 MX crop in the snow. This bike performs so well for me I've decided to hang onto it for another season.

    2013 KTM 450 XC-F Love it!
  8. MURRIETA, Calif. - KTM announces major revisions to its 2015 model year four-stroke lineup. The company also revealed performance, stability and handling upgrades for its two-strokes and minis. 250 SX-F "The 250 SX-F is once again a World Championship winner in MX2 and adds a prestigious AMA Supercross Lites Championship in 2013 and 2014 to its amazing trophy cabinet," KTM said. "The 2013 season was a great success in racing at all levels around the globe. The performance combination of a powerful and lively engine in a lightweight and agile chassis is sure to make the 250 SX-F the star of the show for yet another year." Engine revisions include a lighter clutch basket and new clutch springs for a more consistent behavior under stress and over time as part of the CSS (coil spring steel) one-piece clutch system. The clutch continues to use a Brembo hydraulic system for light operation and controllable modulation. Within the proven DOHC engine are also new O-rings on the oil pump suction screen for increased durability. For 2015, the 250 SX-F continues to use the Keihin engine management system with EFI and a 44mm throttle body, a quality wire harness, lightweight gearbox, and electric starter. Features include: Compact DOHC engine with two overhead camshafts and DLC-coated followers Titanium valves (intake 32.5mm, exhaust 26.5mm) RPM limit of 14,000 rpm Flow optimized ports Forged box-type piston for a low oscillating mass A crankshaft employing a plain big end bearing for longer service intervals New O-rings on the oil pump suction screen for increased durability A multifunctional counter balance shaft, which drives the water pump and timing chain for reduced vibrations An electric starter as standard Lightweight and compact CSS clutch with eight clutch plates and a hard-wearing steel basket New clutch basket with a weight-saving design New clutch springs for more consistent behavior Lightweight five-speed gearbox for precise and easy shifting, adapted for the 250 SX-F An engine management system for a spontaneous throttle response, and an ability to change characteristics or read engine data with an optional User-Setting-Tool 350 SX-F With the bike's low weight, playful agility and a high-revving engine, "it enjoys all of the very best characteristics in a package suited to amateurs and pros alike," KTM said. For 2015, the 350 features a DOHC engine with lightweight titanium valves and DLC-coated followers for spontaneous power delivery, along with a crankshaft that has been designed to increase service intervals. New O-rings increase durability on the oil pump suction screen. An electric starter is standard. A new lighter clutch basket with new clutch springs compliments the CSS clutch with the Brembo hydraulic system for easy and precise control of a 250-agile bike with the power that can match a 450, KTM said. More specifically, the 350 SX-F features: A DOHC Cylinder head with ultra lightweight titanium valves and DLC-coated followers for a spontaneous power delivery and 450-rivaling maximum power A crankshaft that employs a plain big end bearing and force-fitted bearing shells for longer service intervals New O-rings on the oil pump suction screen for increased durability A multifunctional counter balance shaft, which drives the water pump and timing chain for reduced vibrations Electric starter as standard CSS clutch eight clutch plates and a hard-wearing steel basket A new clutch basket with a weight-saving design Lightweight five-speed gearbox for precise, easy shifting adapted for the 350 SX-F An engine management system for a spontaneous throttle response, and the option to change characteristics or read engine data with a separately purchased User-Setting-Tool 450 SX-F The 450 SX-F is the weapon of choice for the Red Bull KTM Factory Race team in the AMA championships thanks to its compact SOHC engine that delivers explosive but controllable power, combined with an agile and stable chassis, KTM noted. The 450 features: A compact 60hp power pack with a single overhead camshaft and the latest electronic fuel injection A single overhead camshaft controlling four ultra-lightweight titanium valves via "extremely rigid" rocker arms, DLC-coated on the intake side Engine speeds of up to 11500 rpm and a three-layer head gasket for durability under the most extreme conditions Bore of 95mm with a lightweight box-in-box type piston for low engine vibrations A crankshaft that employs a plain big-end bearing and force-fitted bearing shells for longer service intervals A side-mounted counter balance shaft that also drives the water pump Electric starter as standard A DDS clutch with Brembo hydraulic actuation -- a compact design that integrates an internal damping system Lightweight five-speed gearbox for effortless shifting New O-rings on the oil pump suction screen for increased durability An engine management system for a spontaneous throttle response and an option to change characteristics or read engine data with a separately purchased User-Setting-Tool.

  9. Hey guys. I picked up a 2011 450 sxf last week. Everything seems in really good order. Has some DNA wheels, dr.d pipe and had some ama numbers on the frame so i know it was raced but it looks super clean. I have no clue what was done to the suspension. None of the tell tale company stickers or setting stickers on it. The front end numbers seem fine. 35mm free/static sag. 73mm rider/race sag(im 200lbs ish). Rear is where things seemed odd. Free/static sag was 51mm and race/rider was 99mm. So that tells me i need a respring front and rear. I adjusted the preload to get the free sag back around 30mm starting point and im going to play around a little with the preload to see where i can get the numbers. Also when i was investigating the clickers on the shock the low speed comp was at 0 clicks... The handle bars were also in a really cramped spot all the way back. Now the point. When i get the rear static sag back in line the rear end still seems low. I measure the seat height at about 37.5"(i think its supposed to be around 39...). now i can't measure my 2012 cause its in supermoto trim so of course its different, but its actually pretty close to this. The SM is just under 37" seat height.... Basically I have my 12 which the suspension was setup for my weight and MX. I am trying to determine which suspension to keep and which to send off to be revalved for supermoto. I just want to make sure i get it in order on the bike before sending it off so we know what to get. Don't want to find out that the shock has been modded to be lowered or something. not that that would be a bad thing on an SM but im running stock wheel base and don't want to fool with lowering just yet. I know this isnt a great representation but both bikes are sitting on the ground. So. Am i seeing things? does 37ish seat height seem lower than factory. I know 11 to 12 made some suspension changes but i thought it was all in valving on the fork. Links all look factory and the same as my 12. The anodized color on the shock lower looks slightly different from 11 to 12 but that may be an age thing.

  12. Hi, Yesterday I started to do a top end rebuild on a 2013 KTM 450sxf and I cant figure out how to find TDC on the crank for these engines. Ive done several rebuilds on YZs that ive had in the past. On the cam there is a notch on the sprocket that lines up with a punch mark on the head. But on the crank I cannot find anything to show TDC. I researched and found there might be a colt that I can take a copper washer out and search for a notch to hit and lock into place? Any help is appreciated! Thanks Alex
  13. The red hot start knob fitted on the new throttle body is helpful in its function but it's implementation is lacking. A remote lever like the carb'd bikes used to have would be handy. It looks like the parts could be a direct swap (cable should thread in where the red knob threads in) but, I've noticed that KTM switched between Magura and Brembo on their clutch lever/master cylinders in recent years. My bike uses a Brembo. Would anyone know if the master cyl cover from an older model which has the hot start features cast in would fit on a current model? Which years were brembos spec'd? Assuming parts compatibility, it looks like this conversion could be accomplished for around 65 bucks with OEM parts from rockymountainmc.

    With the 450 SX‑F, KTM has a winning motorcycle in its range, which derives its potential from a high-capacity engine and a chassis perfectly tuned to the power unit. The 450 SX-F is the no. 1 choice for the official KTM factory team in the AMA Championship. No wonder; the compact SOHC engine guarantees brutal yet controllable power with its revolutionary injection technology. Above all, the 450 SX-F scores highly compared with other large 4-strokes in terms of performance and handling. Ideal for every motocrosser who sees plenty of torque, ample on-tap power and a controllable ride as their complete package. TECHNICAL DETAILS ENGINE Design: single cylinder, 4-stroke, SOHC, 4-Valve Displacement: 449.3 cm³ Bore: 95 mm Stroke: 63.4 mm Starting aid: Electric starter Transmission: 5-gear, claw shifted Engine lubrication: Pressure circulation lubrication with two Eaton pumps Primary transmission: 32:76 Secondary gear ratio: 13:50 Cooling: Water cooling, permanent circulation of coolant by water pump Clutch: Wet multi-disc clutch DDS / Brembo hydraulics Ignition: Contactless controlled fully electronic ignition with digital ignition adjustment CHASSIS Frame: Central tubular frame made from chrome molybdenum steel tubes Fork: WP Suspension Up Side Down 4860 MXMA 4CS Shock absorber: WP Suspension 5018 BAVP DCC Suspension travel Front: 300 mm Suspension travel Rear: 317 mm Brake system: Disc brakes, floating brake calipers Brake discs - diameter front: 260 mm Brake discs - diameter rear: 220 mm Chain: 5/8 x 1/4" Steering head angle: 63.5° Wheel base: 1,495±10 mm Ground clearance (unloaded): 371 mm Seat height (unloaded): 992 mm Total fuel tank capacity approx.: 7.5 l Unleaded premium fuel: (95 RON) Weight without fuel approx.: 106.8 kg

    Andrew Short's 2014 Nationals bike. Cone forks, Trax shock, factory motor, etc.
  22. Hey guys, i just picked up a used 2012 ktm 450 sxf to be my supermoto race bike next year. the bike seems pretty much stock but there is a connector on the left side of the steering stem that I am 99% sure couldnt be factory. Its a 4 pin connector, 2 wires in, 2 wires out(to the Estart switch on the bar). On the estart side of the connector there is a small jumper wire in the other 2 spots. I have found lots of info on adding the ignition map switch but i can't find anything about this connector or if it was factory. There is a small coil of wire just before the connector and the connectors appearance makes me think it was some aftermarket or home brew ignition map switch. This is a carb US 450sxf. thanks!

    4 speed sxf450?

    I was looking at upgrading from my 2013 yz450 to a 2014 sxf450 in a month or so but once i started doing some research on the KTM's i found out that they only run a 4 speed in the Australian model, but the US models get a 5 speed? Why is this and is it possible to get one in Aus with a 5 speed? If not it looks like il be staying on the jap bikes, i mainly ride desert tracks and a little bit of motocross, and dont even bother mentioning the 450exc or any other trail bike aha Cheers
